The CellCheck XL specular microscope uses the latest technologies, algorithms, and and endothelial cell analysis. It is used in clinical practice and for clinical research. This microscope is easy to use and includes auto focus, auto alignment, and auto cell counting. The system is able to capture high quality images of the patient's corneal endothelium by using a patented method that identifies the position of the cellular interface. It has five fixation points for capturing an image, one in the center and in four peripheral sites. This provides a more comprehensive look at the cornea. This specular microscope is especially helpful in cases of keratoconus, corneal transplantation, DSAEK, CXL, and with corneal dystrophies. The CellChek software in this microscope can automatically store locations where data samples are collected.
